Applications
- 9.7.1 High-Resolution Population Mapping — Combining very-high-resolution optical imagery with building footprint extraction and ancillary data to produce sub-100-metre gridded population estimates across a national territory.
- 9.7.2 Daytime/Nighttime Population Shifts — Measuring where people actually are—not just where they live—by fusing satellite nighttime lights, daytime optical imagery, and thermal signatures across the 24-hour cycle.
- 9.7.3 Migration & Urbanization Tracking — Detecting and quantifying population movement and urban expansion by fusing multi-temporal satellite optical, SAR and nightlight imagery into continuous settlement-change intelligence.
- 9.7.4 Demographic Change Inference — Deriving long-run shifts in population age structure, household density and settlement composition by fusing multitemporal satellite imagery with ground-truth census proxies.
- 9.7.5 Refugee/Displacement Estimation — Using multispectral and SAR satellite imagery to detect, count and monitor informal settlements and displacement camps at crisis speed.
